Harry and the Dinos go to Dino World in search of something that might make it grow back quickly… Luckily, help is at hand in the form of Gaston, a French poodle and hairdresser to the stars! He applies a tiny drop of his super-duper hair-growing potion to Harry’s hair and everyone watches in amazement as Harry suddenly develops long flowing locks!

When Harry comes home with exciting tales from his day at school, the Dinos wish that they could go to school too. Harry thinks that Dino World may be the place to look for a Dino school - and lo and behold, when they arrive they find a school ready-and-waiting for them. With Harry as their teacher, the Dinos have a great time learning how to be at school: Trike is appointed board monitor; Patsy demonstrates playing the ukulele for ‘Show and Tell’ and they all discover that recess is the best part of the day!

Harry and the Dinos want to fly their kite, but with no sign of a breeze they are struggling to get it off the ground. Pasty suggests that Dino World may provide the answer, so Harry and the gang jump through the bucket and head off in search of the wind. The only trouble is, there’s not a gust of wind to be found in Dino World either, and ‘The Wind Finders’ still can’t fly their kite. When they meet Nancy the Nanosaurus, they discover that the wind isn’t the only thing missing and before long, ‘The Wind Finders’ have become ‘The Bird Finders’ who in turn, become ‘The Seed Finders’ and ‘The Rain Cloud Finders’! Harry quickly learns through this chain of events that everything in nature depends on everything else and he might just have to wait his turn before he gets to fly his kite.

The Dinos are helping Harry look through his old toys for something he can give to Charley’s new baby cousin.

Determined to locate the rest, Harry and his Dino pals head off to Dino World and embark on a daring block-finding adventure! On their arrival, they encounter Digger Stan, the build-it man, who is busy with his latest road construction project, and Harry and the Dinos offer to lend a hand in return for Stan’s help with their mission. En route, Harry re-discovers some of the toys he used to play with and finding the missing blocks for the new baby also proves to be a bit of a trip down memory lane!

Harry tries to lend a hand, but to his dismay, discovers that he isn’t strong enough! A trip to Dino World is called for to find the solution to Harry’s predicament, and he’s motivated even further when he realises that he needs to be stronger to help Nancy Nanosaurus lift Clown Mountain to retrieve something that has rolled underneath. It’s not long before the Dinos are putting Harry through his paces in the Dino World gym and he’s ready to try his luck on the Dino-Meter Strength Tester. With their new-found strength, Harry and the gang manage to shift Clown Mountain for Nancy before heading home to help Nana with those boxes.

Harry is curious to know what a ‘quest’ is after he sees Sam reading a book about Jason and the Quest for the Golden Fleece. While Mom is explaining, Nana mentions that Mom’s birthday is coming up and Harry and the Dinos decide to go to Dino World to embark on a quest of their own to find the perfect birthday gift.

After jumping through the bucket, Harry and the gang discover an Ancient Greek rowing ship with Medea as the figurehead. By a stroke of luck, she has a whole chest full of quests for them to choose from, including one to find ‘the most amazing necklace ever’ - what could be better for Mom’s birthday?!

But with rivers and lakes to cross and a dancing giant cat to help en route, it isn’t going to be easy!

After giving Mom a necklace with a key-shaped pendant on it, Harry and his Dino pals are dying to know what the key opens and they head to Dino World on their new quest to find the matching lock. Princess Pamela’s castle seems to be the perfect place to start, but the royal pets Max and Muffin have other ideas and decide to take the opportunity to make a getaway – taking the key with them! Princess Pam’s naughty pets lead Harry and the gang on a wild goose chase around Dino World. But as luck would have it, Max and Muffin aren’t so bad after all as they lead Harry and the Dinos to the ideal spot to try out their key: a valley full of doors! It’s just a case of finding the right one and seeing where it leads…

When Harry and the Dinos learn that groups of stars make pictures called constellations, they decide to investigate further! Space Captain Harry and his Dino crew boldly go where no dino has gone before: Dino World!

Harry has something very special to take to Show and Tell: the paper penguin that Nana made for him. But when Trike accidentally drops him into Harry’s bucket, Harry and the gang embark on an epic hot-air balloon tour of Dino World in search of the missing paper penguin. Along the way, they meet Tatsu the dragon who points them in the direction of the Penguin Pole.
